2. Calamaria of the Dresden Museum.— Professor II. B. 

 Geinitz, at the close of fifty-one years of active service as 

 Director of the Dresden Museum, lias contributed* a valuable 

 revision of fossil Calamaria, adding some new forms, and perfect- 

 ing the lists already published, by reconsideration of the nomen- 

 clature and reference to the bibliographical references up to the 

 date of publishing. The report includes three Archoeocalamites 

 from the Culm. From the productive Coal Measures are reported 

 S. species of Catamites, 3 of Calamitina, 5 of Aster ophyllites, 2 

 Anmdaria, 8 Sphenophyllum. 



The Rothliegendes or Dyas furnishes eight representatives of 

 Calamodendron which the author distributes in the genera 

 Catamites, Aster ophy llites, Annularia and Sphenophyllum.

3. Fossil Cephalopoda of the British Museum. — Mr. G. C. 

 Crick, of the Geological Department, has prepared, and the 

 British Museum trustees published, a complete list of the types 

 and figured specimens of Fossil Cephalopoda in the Museum. f 

 Each specimen is entered under the name given it when first 

 figured or described, and additional reference is made to names 

 subsequently applied. The entries are made in alphabetical 

 order of genera. The Index is made alphabetical for species.

4. Two new fossils from Canada. — Prof. J. F. Whiteaves 

 describes, in the Canadian Record of Science for October, 1897, 

 two interesting fossils. Actinosepia Canadensis]^ is represented by 

 a sepiostaire closely resembling that of the modern Sepia, but 

 presenting generic differences from the Montana or Pierre-Fox 

 Hills formation, at South Saskatchewan, opposite the mouth of 

 Swift Current creek. The second§ is a tooth allied to Holop- 

 tychius, from the Upper Arisaig Series at McDonald's Brook, near 

 Arisaig, N. S., supposed to be of the age of the Lower Helder- 

 berg, of the New York series. The specimen is provisionally 

 referred to the genus Dendrodus, under the name Dendrodus 

 Arisaigensis. h. s. w. 



5. Brief notices of some recently described minerals. — Miersite 

 is the name given by L. J. Spencer to a new form of silver iodide 

 crystallizing in the isometric system. It is thus dimorphous with 

 the well-known iodyrite which belongs to the hemimorphic group 

 of the hexagonal system. Miersite has been observed in cubic 

 crystals, showing faces of one or both of the tetrahedrons. It
